[0033]

[0034] The specific processing method is as follows:

[0035] (1) Oxidation roasting

[0036] Add nickel-cobalt sulfide into the rotary kiln through the feeding screw for oxidation and roasting, and the metal sulfide in the material is oxidized into sulfates that are easily soluble in water and low-valent oxides that are soluble in dilute acid, so as to remove sulfur in the material , The purpose of ammonia. The output flue gas enters the flue gas treatment system for dust collection and desulfurization, so as to achieve the emission of flue gas up to standard. During the roas...

Abstract

The invention provides a treatment method of a cobalt-containing material, belonging to the technical field of non-ferrous metal smelting. In the treatment method, through six steps such as peroxidation roasting, sulfuric acid leaching, N902 extraction of copper, chemical iron calcium magnesium removal, P204 extraction and impurity removal, P507 extraction and separation of nickel-cobalt, nickel,cobalt and copper in the nickel-cobalt material are extracted in high recovery, and impurities such as iron, zinc, manganese, calcium, magnesium and the like in the nickel-cobalt material are removed, thereby achieving nickel-cobalt-copper separation and resource comprehensive utilization. According to the treatment method provided by the invention, the process is simple and production cost is relatively low; the adaptability of the method on raw materials is strong and can be used for treating the nickel-cobalt material with complicated components and high copper-zinc-magnesium contents.

Description

technical field [0001] The invention belongs to the technical field of nonferrous metal smelting, and relates to a method for processing nickel and cobalt materials. Background technique [0002] Non-ferrous metals are important materials for national economy and national defense construction, as well as supporting materials for high-tech, refined and cutting-edge technologies. With the development of national economic construction and science and technology, the scope of application of non-ferrous metals has been expanding day by day, and the consumption has increased accordingly, but primary non-ferrous metals can no longer meet the needs. Therefore, it is particularly important to effectively recycle and utilize non-ferrous metal waste. [0003] "Nickel-cobalt material" is a complex material containing cobalt, nickel, copper, iron, calcium, magnesium, lead, zinc, manganese, sulfur, ammonia and other components produced in the metallurgical process of non-ferrous metals....
